Abstract

L'invention concerne des systèmes et des procédés permettant de déterminer la partie ou l'opération d'un ou de plusieurs processus d'activation de batterie secondaire (SCell) à différer ou à redémarrer lorsqu'une tentative d'exécution simultanée d'opérations multiples du ou des processus d'activation de SCell provoquerait une interférence. Par exemple, un réglage de fréquence radio (RF) et/ou un réglage de commande automatique de gain (CAG) pour une activation de SCell peuvent être différés jusqu'à ce qu'une requête automatique de répétition hybride (HARQ) pour l'activation de SCell soit envoyée par un UE à la SCell. Dans un autre exemple, un réglage RF et/ou un réglage CAG correspondant à l'activation d'une première SCell peuvent être différés jusqu'à ce qu'un réglage RF et/ou un réglage CAG correspondant à l'activation d'une seconde SCell soient exécutés.
